Easy Tournament Victories
When playing through the World Tournament mode, players can use a simple strategy to gain an easy victory over the computer opponent. At the start of each match when fighting against the computer tap back twice, and then up/back to push your fighter to the edge of the ring. Wait at the edge until the computer controlled fighter begins to attack. As soon as the computer controlled fighter get near you press forward plus X to warp behind him, and then simply push the other fighter off of the edge of the ring. Exploiting this glitch will allow you to easily win the World Tournament with any character.
